DFKKOP Select is slow

Hi. I am having troubles trying to SELECT data from the table DFKKOP. The thing is I only have the field XBLNR for the WHERE filter and it is not a key field. My SELECT is as follows:

if t_data_folder[] is not initial.

SELECT opbel opupw opupk xblnr bukrs

FROM dfkkop

INTO TABLE t_dfkkop

FOR ALL ENTRIES IN t_data_folder

WHERE xblnr = t_data_folder-xblnr.


The data table t_data_folder is filled with data from a .CSV file from excel. It has around 150 entries and this SELECT is needing about 10 minutes to execute.

Can anybody show me a way to improve the performance?

    Try adding DFKKKO to the select. Use xblnr in DFKKKO to get opbel and then use opbel to get the items in DFKKOP.

    Put an Index on field XBLNR of table DFKKOP

    Transaction SE11 -> Database Table

    menu: GoTo->Indexes -> Create-Button (white sheet) // Indexname should start with "Z"

    Chose: Non-unique index and index on all database systems and add the field by using the button "Table Fields"

    Create the index into the development system and transport to productiv system.

    But take care do not Transport the index to productive while other users are working. It could create a dump.
